What, in your opinion is the most miss-named anime series that gives a totally wrong opinion of what the series is about?

My nomination for the most miss-named anime is Kitty Grade. When it starts you are presented with the two main characters who look like they are in middle school and high school. The situation gets more confusing when the "younger" one keeps drinking champagne. Needless to say the situation is a lot more confused than what is initially presented.
